Get perfect ring gaps with a piston ring filer!

If the gaps in your piston rings are too big, you can lose compression (and therefore power), but if they’re too small, the ends will butt together as the rings expand to operating temperature, which can be disastrous. The right gap size can vary by ring material, bore size, piston material, and application, but the right tool for grinding rings down to the proper size is a piston ring filer. Weekend mechanics can usually get by with a manual crank filer, but professional engine builders may need the speed and repeatable accuracy of an electric filer.
